Hi,

Chrome profiler shows nodes getting deleted for us after clearAll. If you are seeing any items remaining in memory, you can inspect the Retainers panel to find out what keeps them referenced.

Hi,

If you create 'unconnected' links, i.e. connecting to a point of the diagram instead of a node, they get actually connected to the diagram.dummy node instance. Try setting its incomingLinks and outgoingLinks fileds to empty arrays for cleanup; clearAll doesn't do that at this time.

Objects without path to them from root window should get garbage-collected at some point, so these shouldn't be a problem unless you are seeing Chrome show the reachable-from-window icon for them.

Hi,

We tried to set node’s incomingLinks and outgoingLinks to empty array but it didn’t help and tried setting diagram.dummy = null or diagram.dummy.incomingLinks = [] then it worked and all nodes collected by GC


Old code (retained node objects in memory)

               diagram.clearAll();

               diagram.dispose();

               diagram = null;



New Code (removed node objects from memory)

                 diagram.dummy = null;

                 diagram.clearAll();

                 diagram.dispose();

                 diagram = null;

   

I observed the diagram object adt.diagram is retained even after a long time also it is not collected by GC. It has some indirect reference from windows through zone. This is the most reason for retention of diagram object and dummy object which has the collection of incoming links.



When explored actual reference, I found following event listener and delegates from diagram class

  'registerDisposableObject': function registerDisposableObject(bP) {

      window['addEventListener'](b('0x2c'), function () {

        bP[b('0x2d')]();

      });

    }

Could to tell me what could be the reasons for it from diagram and please suggest me some solution?

Hi,

As your suggestion setting function registerDisposableObject as below, resolved window reference from through this function.

MindFusion.AbstractionLayer.registerDisposableObject = function(){};



Still one reference from window through function “createDelegate” keep diagram object alive. Please refer above screenshot. If we could resolve this one, mostly the diagram object will be free for GC collection. Could you please suggest some solution for it?
